ATTACI IMENT FOR TROLLEY-WIRE HANGERS Specification. of Letters Patent.

Patented Sept. 5, 1916.

Application filed November 9, 1915. Serial No. 60,497.

vention, such as will enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to new and useful improvements in attachments for trolley wire hangersand more particularly to that class used/in mines or other places where the suspended wires are in position to come in contact with a person or animal, and my object is to provide non-conducting guards and position the same on opposite sides of the -wire to form a guard therefor.

A further object is to provide means for supporting the guards. And a further object is to so construct the device that it can be applied to use in connection with wire supports of various kinds.

Other objects and advantages will be hereinafter set forth and' more particularly pointed out in the accompanying specification.. In the accompanying drawings which are made a part of this application, Figure 1 is an elevation of *the guard showing one manner of attaching the same to the wire hanger. Fig. 2 is a bottom plan view thereof. Fig. 3 is a sectional view transversely through the guard support. Fig. 4 is an elevation showing a different means of attaching the support to the hanger, and Fig. 5 is a similar view of a still different means of attaching the guard support to the hanger.

Referring tothe drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates a hanger which may be of the usual or any preferred construction and designed to receive at its lower end a clamp 2 which clamp engages a trolley w1re 3 and suspends the wire from a ceiling or roof of a mine or other suitable place, and in order to protect the wire and prevent any one from coming in contact therewith whereby they would be injured from the current passing through the wire, I provide "disturbing the guards 4 which are placed on opposite sides of the wire a distance therefrom and extendmg above and below the wire, said guards belng constructed of any suitable insulating material, preferably wood.

In order to retain the guards in proper position and hold the same spaced from the Wire 3, asupport 5 is provided, said support termlnatlng 1n downwardly extending arms 6 at each end to which the guards 4 are attached by means of bolts 7 or in any suitable manner.

-The supports 5 may be attached to any suitable part of the hanger and as shown in Flgs. 1, 2 and 3, it is attached to the clamp 2 and properly insulated therefrom, while in, Fig. 4 of the drawings the support 8 is formed integral with the bell 9 of the hanger, said bell being likewise insulated from the wire 3. Where the trolley system is already installed, that form of support 10 shown in Fig. 5 may be used which is introduced around the hanger 11 between the bell 9 and the roof of the mine or other object to which the hangers are attached, this form of hanger being also insulated from the hanger in any suitable manner to prevent the current in the wire from passing into the support.

I The guards 4 are constructed of sufficient rigidity and placed a suflicient distance from the trolley as to prevent the guards from coming in contact with the wire, thereby obviating any possibility of the current passing through the guard should the guard be wet or damp.

It will likewise be seen'that this device can be very cheaply constructed,and readily installed either by forming thesame in connection with the parts of the hanger before the hanger is installed or attaching the same to the hanger after installation as shown in Fig. 5 and as the guards extend longitudinally of the trolley wire they will efliciently protect the wire and prevent anyone coming in contact therewith. And it will likewise be seen that in view of the distance between the trolley wire and guards, the trolleys will readily pass along the wire without coming: in contact with the guards or in any manner same.

Having thus fully described my invention what I claim as new and desire to secure Letters Patent of the United States, is

An attachmentfor trolley wires to provide safety guards therefor, comprisin supports adapted to be connected with the hangers of said Wires, said supports comprising horizontal members extending latdistance below the horizontal plane of the trolley Wires, and provided with horizontally spaced pairs of apertures through their lower end portionaguards of non-eonducting material extending longitudinally of the wires on opposite sides thereof in spaced relation thereto and projecting above and below the same, said guards having squared ends adapted to lie in abutting rethe end portions lation to each other at the inner sides of said depending arms at substantially the transverse centers thereof and bolts projecting through the apertures of the lower end portions of said rigid depending arms and of said guards for removably and independently securing said guards to said depending arms In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
